I'd also like to try out my Color Computers with a modern monitor to see if the color aliasing used by some games can be reproduced. I don't have a modern television, but I might still have a crusty old VCR out in the junk pile whose tuner output could be fed into the $15 converter. I’m anxious to hear reports on it. I’ve tried a lot of different things and so far nothing can handle the NTSC color signal that the Apple II puts out. Same with the Atari 800. I just end up with a monochrome screen with lines instead of colors. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com

RE: 8-bit Computer TV Channel Use
Yes, video is tricky. I've just had an experience which emphasizes the topic under discussion. The main problems stem from the fact that these computers output anything but broadcast-standard video. In some cases it was because they were built to a price and it was 'what can we get away with'. In others it was more a case of getting extra features (like colour) almost for free. Just recently I got hold of an Amstrad CPC 464. http://www.classic-computers.org.nz/collection/amstradcpc464.htm Incidentally, one of the better things (for me) about Amstrad machines is that service manuals existed for them. Said manuals are essentially a schematic and a parts list, but that is all that is normally needed. Certainly for the older machines (all the CPCs and PCWs and the earlier PCs) they are not just boardswapper guides. It didn't come with its screen though (dedicated screens were sold with the machine). However British enthusiasts had developed an RGB to SCART cable What are you doing for the PSU (the computer ran off the SMPSU in the monitor IIRC)? for this very problem. Problem for me was that although SCART is a common video interface in Europe, it's rare in New Zealand. However I noted there One problem with SCART (and I don't think it's the cause of your problems) is that it is several interfaces on one connector. In particular there is composite video, RGB video (using the composite pin for sync) and later S-video (using the composite pin for Y and IIRC the 'red' pin for C). Not all devices implement all parts of the interface. In particular UK TVs almost always have the RGB inputs, VCRs did not. The CPC output is RGB video, and AFAIK the CPC-SCART cable is a simple cable with perhaps level-shifting resistors inside. So it will use the RGB pins on the SCART connector. -tony

I really need to do a cap kit on it though, it takes forever to warm up, and the tuning drifts while it’s on and I have to change the channel and then back to get it to lock on again. -- Follow me on twitter: @FozzTexx Check out my blog: http://insentricity.com
